gpppwrap is a graphical user interface to conveniently select a phone number and dial into your ISP. It's very convenient if you use different ISPs, and is based on the GTK GUI libraries. It is only a wrapper around the ppp-on/ppp-off scripts and gives you therefore still the power and flexibility of these scripts. It is written for people who like the power and flexibility of shell and Perl scripts, and also want an idiot-proof way to connect to the Internet.
plircc is a replacement for irexec and irxevent. It implements a modified stack automaton to keep track of the remote control state. Its configuration is far more powerful and easier than the classic .lircrc way. It has OSD support, so you can display many things on the screen for instant visual user feedback. It also tries to monitor the processes to automatically jump to good state when the user launches an application supported by the configuration file.
